CW · OVERVIEW

What an OPC is, and its honest limits

A One Person Company is a private limited company with a single member, introduced by the Companies Act, 2013 to give solo founders limited liability without a nominal second shareholder. Registered in Kolkata, the file sits with ROC Kolkata-I / Kolkata-II.

Being straight about the constraints, because they decide whether an OPC is right for you:

Only a natural person who is an Indian citizen, whether resident in India or not (since 1 April 2021), may form or be a nominee of an OPC. A company cannot.
A person can form only one OPC and be the nominee of only one.
An OPC cannot carry on non-banking financial investment activity.
An OPC cannot be converted into a Section 8 company.
It is not a structure external investors subscribe to. If you expect to raise equity, a private limited company is the better starting point.

CW · WHO IT APPLIES TO

Converting an OPC

There is no longer any size limit that forces an OPC to convert. The old rule requiring conversion once paid-up capital exceeded Rs 50 lakh or average turnover exceeded Rs 2 crore was removed from 1 April 2021 by the Companies (Incorporation) Second Amendment Rules, 2021. An OPC converts into a private or public limited company voluntarily, usually when it needs a second shareholder or outside investment, by increasing its members and directors to the minimum for the new class.

Conversion is filed with ROC Kolkata-I / Kolkata-II, the same registrar that holds the original incorporation. Conversion is never forced by size, but it does carry its own filings, a fresh set of statutory registers and a change in the annual compliance load, so plan it before a fundraise rather than during one.

CW · JURISDICTION

West Bengal professional tax

West Bengal levies professional tax. An entity registered in Kolkata must obtain professional tax registration and file the associated returns, which is an ongoing obligation rather than a one-time cost.

An OPC in Kolkata picks this up from incorporation, administered by the Directorate of Commercial Taxes, West Bengal. The liability attaches to the company and to the sole director regardless of profitability, and it carries periodic returns rather than being a one-time registration.

For a solo founder this matters more than it looks. You are the entity and the director, so both limbs of the West Bengal professional tax obligation land on the same person.

CW · PROCESS

The process, step by step in Kolkata

Step 1. DSC for the member and director

A Class 3 DSC is issued for the sole member, who is usually also the sole director.

Step 2. Obtain nominee consent in INC-3

The nominee's written consent is obtained before filing. Without it the application cannot proceed, and this is the step that most commonly delays an OPC.

Step 3. Name reservation via SPICe+ Part A

The name is reserved, and must carry the OPC suffix in the prescribed form.

Step 4. Draft MOA and AOA

The MOA records the nominee, and the registered office clause states a Kolkata address.

Step 5. File SPICe+ Part B

The incorporation application is filed and processed centrally by the Central Registration Centre (CRC); the company's file then sits with ROC Kolkata-I / Kolkata-II. West Bengal stamp duty on MOA and AOA is e-stamped through the same gateway.

Step 6. Certificate of Incorporation

The CRC issues the COI with CIN, along with PAN and TAN. Post-incorporation filings go to ROC Kolkata-I / Kolkata-II.

Step 7. Post-incorporation

Bank account, INC-20A within 180 days, and West Bengal professional tax registration.

CW · COMMON MISTAKES

Mistakes we see on Kolkata OPC files

Choosing an OPC while planning to raise equity within a year. Investors do not subscribe to an OPC, so conversion becomes an immediate cost.
Leaving the nominee until the filing stage. INC-3 consent is mandatory and cannot be worked around.
Relying on the old conversion thresholds. Many articles still say an OPC must convert above Rs 50 lakh capital or Rs 2 crore turnover; that rule was removed from 1 April 2021, so do not plan, or pay for, a conversion on that basis.
Filing MGT-7 instead of MGT-7A. An OPC uses the abridged form.

CW · LOCAL SCENARIO

A Kolkata example

A Kolkata solo consultant incorporated an OPC for the limited liability, then agreed terms with an angel investor a year later. Investors cannot hold shares in an OPC alongside the founder, so the company first had to convert into a private limited company, adding a second member and director and filing the conversion with the ROC, before the investment could close. Choosing a private limited company at the outset would have cost slightly more and avoided the delay.

Illustrative scenario based on typical file patterns. Not a named client engagement.

CW · FAQ

OPC Registration in Kolkata - questions we get

Which registrar handles a Kolkata OPC?

ROC Kolkata-I / Kolkata-II. ROC Kolkata was split into two offices on 16 February 2026. Kolkata-I covers the district of Kolkata and the State of Sikkim; Kolkata-II covers the rest of West Bengal. Both sit in Kolkata but hold separate files.

Is a nominee compulsory?

Yes. Every OPC must name a nominee who consents in Form INC-3. The nominee must be a natural person and an Indian citizen (resident in India or not, since 1 April 2021), and can be the nominee of only one OPC.

When must an OPC convert?

Never, as a matter of law. Since 1 April 2021 there is no paid-up capital or turnover limit that forces conversion (Companies (Incorporation) Second Amendment Rules, 2021). An OPC converts voluntarily, typically when it wants to add shareholders or raise investment.

Can I run more than one OPC?

No. A person may form only one OPC and be the nominee of only one.

Does an OPC hold an AGM?

No. An OPC is exempt from holding an annual general meeting, and files MGT-7A rather than MGT-7.

Does an OPC in Kolkata pay professional tax?

Yes. West Bengal levies professional tax, administered by the Directorate of Commercial Taxes, West Bengal.
